GetPointCount returning 0 points (if amount is over int.max)

[DriesDeRidder]

Hi,

I'm working with a very big point cloud of around 114gb. When i try to convert it it always succeeds within 1second which obviously is wrong.
I'm trying to debug it but I don't get any errors. So in the output log I see ut say 'Total points: 0'. which is also not possible ofcourse.

I'm trying to debug it and here I see my reader is not null but my writer is null.

it then goes to the next line but shouldn't this be '||' instead of '&&'. according to the error log below that's what should happen. maybe the log needs to be changed then?

Also I have found that my issue probably lies in the max range of the variables.

As you can see I my point count has reached '4294967295' which is the max range of an unsigned long (for 32bit system). Any quick way around this? I'm currently rebuilding everything to ulong and i'll report back

Are you converting within the Unity editor plugin?
If yes, can you try using the standalone converter also:
https://github.com/unitycoder/PointCloudConverter

other workaround would be to split to source cloud into multiple files.. (if this is one off conversion)

I'm already using the standalone converter. I'll try the splitting

[unitycoder]

btw. i tested pointcount value as long (instead of int) here https://github.com/unitycoder/PointCloudConverter/tree/dev2
if you are able to test it, i can merge to main. (or if i find large file to test myself)

[DriesDeRidder]

Alright we’re testing it now!

FYI, the converter works. It does take up a lot of RAM in Unity because it has to load a lot of files but it works which is the most important ofcourse

[unitycoder]

btw. are you using Packed format? (it would reduce files/used memory)

[DriesDeRidder]

Yes I do. It does improve memory usage but it still is a lot sometimes. we did find a way to decrease memory usage but it's quite a complex setup. We have multiple point cloud viewers and some have release memory on and some don't and the ones that don't are exported at lower settings and are there to fill up the background and when you get closer a higher resolution point cloud gets loaded. It's quite a setup but gives good results for very high density and large point clouds (100gb+) for around 300x50m

[unitycoder]

so the reason to use multiple viewers is to have some points visible (instead of the distant tiles completely culled out) ?

would it make sense to
have minimum point count setting for tiles, that it doesn't get down to 0, even when viewed from far away?

Or have you tried any of the shaders that allow scaling point size by distance? (so that further away points are larger)
